Giotto Premium Plus: Pressure gauge sticks on .15 bar when cold
Not sure when this started happening but I recently noticed the boiler pressure gauge no longer returns to zero when cold. It bottoms out around .15 bar. It otherwise appears to work as expected, though I have no idea whether it's reflecting the actual boiler pressure.
Any ideas what might be causing this?
It's probably a small rock of limescale blocking the capillary tube to the gauge. Can be a sign that descale/service is required
